Abstract: The relation between low temperature annealing with microstructure and properties of 1Cr18Ni9Ti stainless steel after cold deformation was investgated. The experimental results show that after low temperature annealing, the microstructure of the steel has been changed apparently, the dislocation configuration was changed from high density dislocasion tangles to dislocation cells and networks. The second phase particles were precipitated during annealing at 450℃, and the strength (σb, σ0.002-) and hardness（HV） were greatly increased. Based on the experimental results, the strengthening mechanism of 1Cr18Ni9Ti stainless steel at various annealing temperature range was given.
